Greetings,
I have come across a computer running Fedora 20 X86_64 that is
basically unusable. I would really appreciate your help to:
1) figure out and fix the current problem (including: would
installing fedora 22 help or make things worse because of
dropped support for some hw component, etc?)
2) even more important: help me define a general, systematic procedure
to investigate what exactly causes certain problems on Fedora and
Linux in general, in all
cases like this. I ask because I just realized that I am not
up to date anymore on this particular topic, and it is a general
interset question, isn't it?
Now the facts: that computer has a dual core CPU and 8GB of RAM, but it
is so slow that when I open any terminal in X, under any window/desktop
manager, if I write a long command at the prompt, then realize I made a
typo
10 characters before the cursor, and hit backspace, it takes 2/3 seconds
to go back to that point.
If I open libre office or ANY OTHER text editor, and move the trackball
to select a sentence,
it takes seconds to see it highlighted. If I then click on another part
of the file
to paste the text there, it is another 2 seconds to see the cursor blink
in that new
position. Ditto for scrolling, in ANY program that supports it: press
PageDown, wait seconds
to see the corresponding text.
My **feeling** is that there is some biiig misconfiguration at the
graphic driver level,
but it's just a feeling. As I said, besides fixing THIS computer, I
really want to refresh all my knowledge on how to investigate properly
any case like this.
Outputs of lspci, /proc information are below. If I need to run other
tests, just ask.
Any feedback is welcome, thanks in advance,
Marco
